 Sa fe ty an d Regu lat ory      phn- 2182_002v000   May 2011   I  Sa fet y a nd regulat ory inform at ion . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .  . . . . This section describes important safety and regulatory guidelines that must be observed by personnel installing or operating PTP 250 equipment. I m port ant  safet y inform at ion WARNING  To prevent loss of life or physical injury, observe the safety guidelines in this section. Pow er line s Exercise extreme care when installing antennas near power lines. W ork ing at  he ight s Exercise extreme care when working at heights. Grounding and pr ot e ctive  e a rt h The Outdoor Unit (ODU) must be properly grounded to protect against lightning. It is the user’s responsibility to install the equipment in accordance with national regulations. In the USA, follow Section 810 of the National Electric Code, ANSI/NFPA No.70-1984 (USA). In Canada, follow Section 54 of the Canadian Electrical Code. These codes describe correct installation procedures for grounding the outdoor unit, mast, lead-in wire and discharge unit, size of grounding conductors and connection requirements for grounding electrodes. Other regulations may apply in different countries and therefore it is recommended that installation of the outdoor unit be contracted to a professional installer.
Safet y  and Regulatory       phn- 2 182_002v 000 I I   May 2011  Using t he cor r e ct  pow er supply Always use the Motorola Power over Ethernet injector unit (PoE power supply) or Powered Indoor Unit (PIDU Plus) to power the ODU. Failure to use the correct power supply could result in equipment damage and will invalidate the safety certification and may cause a safety hazard. Alt ernat ive DC supply  If the PTP 250 is to be powered from a DC supply (either as the primary power source or as a backup to the AC supply), the DC supply must be input to the ODU via a PIDU (not a PoE power supply). The DC supply must be connected to the PIDU DC IN terminals. The DC supply must comply with the following requirements: • The voltage and polarity is correct and is applied to the correct terminals in the PIDU. • The power source is rated as Safety Extra Low Voltage (SELV). • The power source is rated to supply at least 1 A continuously. • The power source cannot provide more than the Energy Hazard Limit as defined by IEC/EN/UL60950-1, Clause 2.5, Limited Power (The Energy Hazard Limit is 240VA). Pow ering dow n be fore servicing Always power down and unplug the equipment before servicing. Lightning pr ot e ction  unit  ( LPU)  Do not remove the LPU printed circuit board when the LPU is connected to the power supply, as high voltages are present. N on - M ot orola  pow e r  supply  Safety may be compromised if a different power supply is used than the one supplied by Motorola as part of the system.
 Safet y  and Regulatory    phn- 2182_002v000   May 2011   III  Drop ca ble t este r  The drop cable tester must NEVER be used at the ODU end connected to power from the PoE power supply.  It must only be used at the bottom of the mast with a multimeter. This is because the PoE power supply voltage exceeds the limit allowed in some countries for safe handling in wet conditions and therefore may create a safety hazard. Prim ary disconne ct de vice  The main power supply is the primary disconnect device. Ex t ernal ca bles Safety may be compromised if outdoor rated cables are not used for connections that will be exposed to the outdoor environment. RF exposure nea r  t he a nt e nna Strong radio frequency (RF) fields will be present close to the antenna when the transmitter is on. Always turn off the power to the ODU before undertaking maintenance activities in front of the antenna. Minim um  sepa ra t ion dist a nces Install the ODUs so as to provide and maintain the minimum separation distances from all persons. The minimum separation distances for each frequency variant are specified in Calculated distances and power compliance margins on page 4-25.
Safet y  and Regulatory       phn- 2 182_002v 000 I V  May 2011  I m port ant  r e gulat or y inform a t ion Operation of the PTP 250 product involves its use as an unlicensed device in frequency bands where it is not allowed to cause interference to licensed services (called primary users of the bands). Radar a voida nce In some countries radar systems are the primary users and the regulators have devised special requirements to protect their operation from interference caused by unlicensed devices.  The unlicensed devices are required to detect the presence of radar systems and avoid co-channel operation with the radar systems. The PTP 250 system provides detection and avoidance functionality for countries and frequency bands requiring protection for radar systems. Installers and users are reminded that they must follow local regulations with regard to any requirements for radar detection as well as transmitted power level.  This can be achieved by using the correct country code for the product concerned.  Failure to follow this could leave the installer and/or user liable to civil and/or criminal penalties. Contact the Motorola helpdesk if you are unsure about any specific areas where you need guidance.

Overv iew  of the PTP 250  Chapt er  1 Product descr ipt ion     phn- 2 182_002v 000 1-2  May 2011  Ove rvie w  of t he PTP 2 5 0  This section introduces the key features, typical uses, product variants and components of the PTP 250. Purpose  Motorola PTP 250 products are designed for Ethernet bridging over point-to-point microwave links in the unlicensed bands 5.4 GHz (ETSI Band B) and 5.8 GHz (ETSI Band C and FCC ISM band). Users must ensure that the links comply with local operating regulations. The PTP 250 is used to create a transparent bridge between two segments of the operator’s network. This bridge can be treated as a virtual wired connection between two points. Key feat ur e s The key features of the PTP 250 include: • Orthogonal Frequency Division Multiplexing (OFDM) modulation and Multiple-Input Multiple-Output (MIMO) techniques. • Wireless connections of up to 54 km (34 miles) in near line-of-sight conditions. • High link availability, through the use of adaptive modulation techniques that dynamically reduce the data rate in severe or adverse conditions. • High-sensitivity antennas for improved signal recovery. • A built-in web server for advanced management capabilities including detailed radio signal diagnosis. • Password control and encryption. Be nefit  of t he chosen bands The products operate in bands that offer the dual benefits of high data throughput and good radio propagation characteristics. The wide band of spectrum available is subdivided into several channels such that multiple systems can operate in the vicinity without causing interference to one another.
PTP 250 User Guide  Overview of the PTP 250   phn- 2182_002v000   May 2011   1-3  8 0 2 .1 1 n device  PTP250 uses 802.11n encoding and radio transmission. In areas where the PTP 250 co-exists with 802.11a and 802.11n devices, the PTP 250 detects the 802.11a and 802.11n radio signals and chooses a clear channel away from any interference. Avoiding int erference  from  nearby de vices At initialization, the products monitor the available frequency channels to find a channel that is clear of interference.  Typical deploym e nt  The PTP 250 bridge consists of a pair of identical units, one deployed at each end of the link. The radio link operates on a single frequency channel. One unit is configured as a master and the other as a slave. The master unit takes responsibility for controlling the link in both directions. The bridge is aimed at a wide range of applications. One example is an enterprise that needs to connect together the Local Area Network (LAN) of two or more buildings as shown in Figure 1-1.  Figure 1 - 1   Typical PTP 250 bridge deploym ent  ( grounding not shown)

PTP and light ning pr ot e ct ion  The PoE power supply meets the low level static discharge specifications identified in Electromagnetic compatibility (EMC) compliance on page 4-22 but does not provide lightning or surge suppression. The amount of lightning protection is dependent on regulatory and end user requirements. The standard ODU is fitted with surge limiting circuits and other features to minimize the risk of damage due to nearby lightning strikes. To be fully effective, these standard features require some additional equipment to be configured as part of the system installation. WARNING  The units are not designed to survive direct lightning strike. For this reason they must not be installed in ‘Zone A’, as defined in Lightning protection zones on page 2-11. Mounting in Zone A may put equipment, structures and life at risk. Out door connections The term ‘drop cable’ refers to the cable that is used for all connections that terminate outside the building, for example, connections between the ODU, LPU and PoE power supply.

PTP 250 User Guide  Wir eless operation   phn- 2182_002v000   May 2011   1-17  W ireless ope rat ion This section describes how PTP 250 wireless links are operated, including modulation modes, power control and security. W ireless Tra nsm ission s  The PTP 250 uses Time Division Duplexing (TDD) transmission, which means that a single frequency channel is used for both Transmit and Receive. This is handled automatically by the radio. The PTP 250 transmits using Orthogonal Frequency Division Multiplexing (OFDM). This wideband signal consists of many equally spaced sub-carriers. Although each sub-carrier is modulated at a low rate using conventional modulation schemes, the resultant data rate from all the sub-carriers is high.  The channel width of the OFDM signal is configurable to one of two values:  20 MHz or 40 MHz. The higher channel width provides greater link capacity at the expense of using more spectrum. The lower channel width provides better receiver sensitivity and can also be appropriate where the amount of free spectrum is limited. Each channel is offset in center frequency from its neighboring channel by 20 MHz. Spe ct r um  m ana gem ent  At system start-up, the spectrum management feature of the PTP 250 monitors the available wireless spectrum and directs both ends of the wireless link to operate on a channel with a minimum level of co-channel and adjacent channel interference.  Alternatively, the user can specify a single channel to use (or several to be chosen from) at the master unit. Adapt ive m odula t ion The PTP 250 can transport data over the wireless link using different modulation modes. For a given channel width, each modulation mode transports data at a fixed rate. Also, the receiver requires a given signal to noise ratio in order to successfully demodulate a given modulation mode. Although the more complex modulations will transport data at a much higher rate than the less complex modulation modes, the receiver requires a much higher signal to noise ratio.
Wir eless operation  Chapt er  1 Product descr ipt ion     phn- 2 182_002v 000 1-18  May 2011  The system provides an adaptive modulation scheme where the receiver constantly monitors the quality of the received signal and notifies the far end of the link of the optimum modulation mode with which to transmit. In this way, optimum capacity is achieved at all times.  NOTE PTP LINKPlanner includes an estimate of mean data rate, the data rate provided by each modulation and the percentage of time spent in each modulation mode. MI MO Multiple-Input Multiple-Output (MIMO) techniques provide protection against fading and increase the probability that the receiver will decode a usable signal. When the effects of MIMO are combined with those of OFDM techniques and a high link budget, there is a high probability of a robust connection. The PTP 250 transmits two signals on the same radio frequency, one of which is vertically polarized and the other horizontally polarized. The system also has the ability to adapt between two modes of operation: • Dual Payload: When the radio channel conditions allow, the system will transmit two different and parallel data streams, one on the vertical channel and one on the horizontal channel. This doubles the capacity of the system. • Single Payload: As the radio channel becomes more challenging, the system has the ability to detect this and switch to a mode which transmits the same data stream on both vertical and horizontal channels. This provides polar diversity and is another key feature which allows the system to operate in challenging radio channels. The switching between modes is automatically controlled by the adaptive modulation feature described in Adaptive modulation on page 1-17.
PTP 250 User Guide  Wir eless operation   phn- 2182_002v000   May 2011   1-19  Ra da r a voida nce In regions where protection of radars is part of the local regulations, the PTP 250 must detect interference from radar-like systems and avoid co-channel operation with these systems. To meet this requirement, the PTP 250 implements the following features: ETSI  regulat ions The regulations have radar detection requirements for both master and slave devices. The requirements for a master device are: • The device can only transmit on available channels, of which there are none at initial power up. The radar detection algorithm will always scan a usable channel for 60 seconds (channel availability check) for radar interference before making the channel an available channel. • As a result of this compulsory channel scan, there is a service outage of at least 60 seconds every time radar is detected, and the installation time is extended by at least 60 seconds even if no radar is detected on the channel. • When operating on a channel, the spectrum monitoring algorithm implements a radar detection function (in-service monitoring) which looks for impulsive interference on the operating channel. If impulsive interference is detected, spectrum management will mark the current operating channel as having detected radar (unavailable channel) and initiate a channel hop to an available channel. The previous operating channel will remain in the unavailable state for 30 minutes after the impulsive interference pulse was detected. • After the 30 minutes have expired the channel will be returned to the usable channel pool. • There is a secondary requirement for bands requiring radar avoidance. Regulators have mandated that products provide an approximately even loading of the spectrum across all devices. In general, this prevents operation with fixed frequency allocations. However, ETSI regulations do allow frequency planning of networks (as that has the effect of spreading the load across the spectrum). NOTE   The Master device will not initiate any transmissions on channels which overlap the band 5600-5650 MHz as the radar detection requirements are more severe.
Wir eless operation  Chapt er  1 Product descr ipt ion     phn- 2 182_002v 000 1-20  May 2011  The requirements for a slave device are: • The slave device can only transmit after receiving a transmission from its associated master to demonstrate that the channel is an available channel. • The slave device is required to vacate the channel when the master device has detected a radar signal. • The slave device is also required to perform in-service monitoring and will stop transmitting on a channel having detected a radar signal (having informed the master device) and will not re-use the channel for thirty minutes. • Once the slave device has detected a radar on a channel, it will perform a channel availability check before transmitting again on the channel. • The slave device is also required to perform Channel Availability Check (CAC) measurements before responding to a master transmission, but this requirement only applies after the slave has detected a radar signal on the channel.  Securit y The PTP 250 supports 48-bit proprietary encryption for data transmitted over the wireless link. Count r y of operat ion Some aspects of wireless operation are controlled, enforced or restricted according to country of operation. The Country Code must be set in the user interface by the user at first login. The Country Code setting affects the following aspects of wireless operation: • Maximum transmit power • Radar avoidance • Transmit power reduction in edge channels • Frequency range • Channel plan CAUTION To avoid possible enforcement action by the country regulator, always operate links in accordance with local regulations.

Using fr e quency planning Networks will benefit from the use of fixed channel allocations if (a) the network consists of multiple PTP links, and (b) RF interference predominantly arises from equipment in the same network. Frequency planning is the exercise of assigning operating channels to PTP units so as to minimize RF interference between links. Frequency planning must consider interference from any PTP unit to any other PTP unit in the network. Low levels of interference normally allow for stable operation and high link capacity. The frequency planning task is made more straightforward by use of the following techniques: • Using several different channels • Separating units located on the same mast • Using high performance (directional) external antennas For help with planning networks, refer to Chapter 2 Planning considerations, or contact a Motorola distributor or re-seller.

Spect rum  planning  Chapt er  2 Planning consider at ions     phn- 2 182_002v 000 2-2  May 2011  Spectrum  planning This section describes the regulatory restrictions that affect radio spectrum usage. Each frequency variant has specific regulatory restrictions that affect frequency range, radar avoidance and channel width usage. Ava ila ble spect r um   Ensure the link is configured to conform to local regulatory requirements. The available spectrum for operation depends on the country of operation: • The 5.4 GHz band is available in all EU countries. • The 5.8 GHz band is currently only available in a limited number of EU countries (UK, Eire, Norway, Denmark, Germany and Spain). Certain regulations have allocated certain channels as unavailable for use: • Europe has allocated part of the 5.4 GHz band to weather radar. • The UK and some other European countries have allocated part of the 5.8 GHz band to Road Transport and Traffic Telematics (RTTT) systems. For examples of these restrictions, refer to Examples of regulatory limits on page 4-32. Where regulatory restrictions apply to certain channels, these channels are barred automatically by the use of the correct country setting. For example, at 5.8 GHz in the UK and some other European countries, the RTTT band 5795 MHz to 5815 MHz is barred. With the appropriate configuration for a country in this region, the PTP 250 will not operate on channels within this band. The number and identity of channels barred by the country selection is dependent on the channel width selected. NOTE  For the connectorized model, when using external antennas of higher gain than the appropriate integrated antenna, the regulations may require the maximum transmit power to be reduced. To ensure that regulatory requirements are met for connectorized installations, refer to Calculating EIRP for connectorized units on page 4-30.
PTP 250 User Guide  Spect rum  planning   phn- 2182_002v000   May 2011   2-3  Frequency selection The PTP 250 fully conforms to regional regulatory requirements for radar avoidance. In regions that mandate DFS, the unit first ensures that there is no radar activity on a given channel for a period of 60 seconds before radiating on that channel. Once a channel has been selected for operation, the unit will continually monitor for radar activity on the operating channel.  If detected, it will immediately cease radiating and attempt to find a new channel.  Radar avoidance requirements in the 5.4 GHz band are defined as follows: • For the EU: in specification EN 301-893 version V1.5.1. Radar avoidance at 5.8 GHz is applicable to EU operation (not FCC/IC) and the requirements are defined in EN 302 502. Cha nnel w idt h Select the required channel width for the link (20 MHz or 40 MHz). The wider channel has the greater the capacity. As narrower channel widths take up less spectrum, selecting a narrow channel width may be a better choice when operating in locations where the spectrum is very busy.

Pow e r  supply sele ct ion Select a suitable power supply unit for the PTP 250. The only supported units are the PoE power supply (included in PTP 250 kits) or the PTP 300/500/600 Series PIDU. The PoE power supply is suitable for the majority of installations, but the PIDU is required in the following situations: • When a -48 V DC power supply is required, either as the primary supply or as a backup to the AC mains. • When an extended operating temperature range is required for the mains powering system, for example when the indoor equipment is in a building without temperature control or air conditioning. For PIDU ordering information, see Alternative components on page 4-9. The power supply unit must be installed in an indoor location with no possibility of condensation, with an ambient temperature within the specified operating range of the product; see Power supply unit specifications on page 4-12.

Antennas and equipment mounted on towers or buildings will subject the mounting structure to significant lateral forces when there is appreciable wind.  Antennas are normally specified by the amount of force (in pounds) for specific wind strengths. The magnitude of the force depends on both the wind strength and size of the antenna. The ODU, with or without the integral antenna, is essentially a flat structure. The magnitude of the lateral force can be estimated from surface area and wind speed.

PTP LINKPlanner is recommended.  Ra nge and obst a cle s Calculate the range of the link and identify any obstacles that may affect radio performance. Perform a survey to identify all the obstructions (such as trees or buildings) in the path and to assess the risk of interference. This information is necessary in order to achieve an accurate link feasibility assessment. NOTE When higher gain connectorized antennas are used, reduce the transmit power to ensure that the receiver signal level does not exceed -20 dBm. PTP LI N KPla nner The Motorola PTP LINKPlanner software and user guide may be downloaded from http://www.motorola.com/ptp/support.  PTP LINKPlanner imports path profiles and predicts data rates and reliability over the path. It allows the system designer to try different antenna heights and RF power settings. It outputs an installation report that defines the parameters to be used for configuration, alignment and operation. The installation report can be used to compare the predicted and actual performance of the link.

Calculat ing pa t h loss The path loss is the sum of the attenuation of the path if there were no obstacles in the way (Free Space Path Loss), the attenuation caused by obstacles (Excess Path Loss) and a margin to allow for possible fading of the radio signal (Fade Margin). The calculation of Equation 2-1 needs to be performed to judge whether a particular link can be installed.

When the link has been installed, web pages provide information about the link loss currently measured by the equipment, both instantaneously and averaged. The averaged value will require maximum seasonal fading to be added, and then the radio reliability of the link can be computed.

However the integrated units may not be sufficient in some areas, for example: • Where the path is heavily obscured by dense woodland on an NLOS link. • Where long LOS links (>23 km or >14 miles) are required.  • Where there are known to be high levels of interference. PTP LINKPlanner can be used to identify these areas of marginal performance. In these areas, connectorized ODUs and external antennas should be used. The external antennas can be either dual-polarization (as the integrated antenna) or two single polarized antennas can be used in a spatially diverse configuration.  It is expected that the dual-polarization antennas would normally be used to simplify the installation process; spatially diverse antennas may provide additional fade margin on very long LOS links where there is evidence of correlation of the fading characteristics on Vertical and Horizontal polarizations.

The actual degree of protection required depends on local conditions and applicable local regulations. Motorola recommends that PTP 250 installation is contracted to a professional installer. WARNING Electro-magnetic discharge (lightning) damage is not covered under warranty. The recommendations in this guide, when followed correctly, give the user the best protection from the harmful effects of EMD. However 100% protection is neither implied nor possible. Sta ndards Full details of lightning protection methods and requirements can be found in the international standards IEC 61024-1 and IEC 61312-1, the U.S. National Electric Code ANSI/NFPA No. 70-1984 or section 54 of the Canadian Electric Code. Light ning pr ot e ct ion zone s The ‘rolling sphere method’ (Figure 2-1) is used to determine where it is safe to mount equipment.  An imaginary sphere, typically 50 meters in radius, is rolled over the structure. Where the sphere rests against the ground and a strike termination device (such as a finial or ground bar), all the space under the sphere is considered to be in the zone of protection (Zone B). Similarly, where the sphere rests on two finials, the space under the sphere is considered to be in the zone of protection.

Do not mount equipment in this zone. • Zone B: In this zone, direct EMD (lightning) effects are still possible, but mounting in this zone significantly reduces the possibility of a direct strike. Mount equipment in this zone. WARNING  Never mount equipment in Zone A. Mounting in Zone A may put equipment, structures and life at risk.

I P int erfa ce Choose an IP address for the IP interface of the ODU management agent. The IP address must be unique and valid for the connected network segment. Ensure that the design of the data network permits bi-directional routing of IP datagrams between network management systems and the ODUs. For example, ensure that the gateway IP address identifies a router or other gateway that provides access to the rest of the data network. Back t o back link s Do not use direct cabled connections between the data ports of two PoE power supplies. Where two or more links are deployed in a chain, always use an Ethernet switch or router to interconnect the links at a relay point. ‘Green Et hernet ’ sw it ches Do not connect PTP 250 units to Ethernet networking products that control the level of the transmitted Ethernet signal based on the measured length of the Ethernet link, for example Green Ethernet products manufactured by D-Link Corporation. The Ethernet interfaces in these networking products do not work correctly when connected directly to the PoE power supply.

Ant enna specificat ions  Chapt er  4 Reference inform ation     phn- 2 182_002v 000 4-14  May 2011  Ant e nna specificat ions This section contains specifications of the antennas that are approved by the FCC for use with the connectorized ODUs. Ant e nna selection crit eria The main selection criterion is the required antenna gain. The secondary criterion is the ease of mounting and alignment. For example, the Radio Waves Parabolic dishes are supplied with a mount that allows adjustment for alignment independent of the actual antenna mounting. This type of antenna is much easier to align than those that have to be rotated around the mounting pole for alignment. N on - FCC r egions In non-FCC regions, antenna choice is not restricted, but any region specific EIRP limit must be obeyed by reducing the maximum transmit power, see Calculating EIRP for connectorized units on page 4-30. FCC re gions In FCC regions, antenna choice is restricted as described in 5.8 GHz FCC antenna restrictions on page 4-15. The maximum permitted antenna gain depends upon product variant and channel width, as specified in Calculating EIRP for connectorized units on page 4-30.
PTP 250 User Guide  Ant enna specificat ions   phn- 2182_002v000   May 2011   4-15   5 .8  GHz FCC ant enna restrictions In FCC regions in the 5.8 GHz band, external antennas from the lists in Table 4-13 can be used with the Connectorized version of the PTP 250. These are approved by the FCC for use with the product and are constrained by the following limit for Single/Dual Polarization Parabolic Dish Antennas: up to 37.6 dBi per polarization or antenna. In FCC regions when using external antennas, cable loss between the connectorized ODU and the antenna ports must not be less than 1.2 dB. CAUTION Antennas not included in this table, or those having a gain greater than the specified maximum, are strictly prohibited for use with the PTP 250 in the 5.8 GHz band.

Max im um  pe r m it t ed EI RP In most countries, operation of products in the band 5470 MHz to 5725 MHz is constrained by an EIRP limit. The constraint is that the EIRP must not exceed 30 dBm or (17 + 10 x Log Channel width) dBm.   In some countries, operation of products in the band 5725 MHz to 5875 MHz is constrained by an EIRP limit. The constraint is that the EIRP must not exceed  36 dBm or (23 + 10 x Log Channel width) dBm.   For examples of countries that impose an EIRP limit, refer to Table 4-23.

Aligning a nt enna s Use this procedure to align linked antennas (master and slave), whether integrated or connectorized.  Prior to alignment, ensure that the following parameters are available: • Location of both sites (latitude and longitude). • Bearing to the other end of the link for both sites. • Prediction of receive signal level for both ends of the link. • Prediction of link loss. PTP LINKPlanner provides all of these parameters in the form of an installation report. If a connectorized ODU is installed at either site with two separate antennas for spatial diversity, refer to Aligning separate antennas for spatial diversity on page 6-27 before starting alignment.
Aligning antennas  Chapter  6 Configurat ion and alignm ent      phn- 2 182_002v 000 6-26  May 2011  NOTE To achieve best results, make small incremental changes to elevation and azimuth. CAUTION The action of tightening the mounting bolts can alter antenna alignment. This can be helpful when fine-tuning alignment, but it can also lead to misalignment. To prevent misalignment, continue to monitor receive signal level during final tightening of the bolts. To align the antennas, proceed as follows: 1   At each end of the link, adjust the antenna to point at the other end of the link. This should be done with the aid of a compass. 2   Without moving the master antenna, adjust the elevation and azimuth of the slave antenna to achieve the highest receive signal level (using one of the recommended methods in Monitoring received signal level on page 6-27). 3   Without moving the Slave antenna, adjust the elevation and azimuth of the Master antenna to achieve the highest receive signal level (using one of the recommended methods). 4   Repeat steps 2 and 3 as necessary to fine-tune the alignment to find the center of the beam. 5   When the antennas have been aligned on the center of the beam, verify that the receive level is within the predicted range (from the installation report). If this is not the case, go back to step 2. The current value of receive level can be verified by using Graphical alignment on page 6-29 or by selecting menu option Status and monitoring the Receive Power attribute on the System Status page. 6   If after repeated attempts to align, the receive level still does not lie within the predicted range, this may be because the  data provided to the prediction tool (such as PTP LINKPlanner) is inaccurate. For example estimates of path obstructions, antenna heights or site locations may be inaccurate. Check this data and update the prediction as necessary. 7   Once the antennas have been aligned correctly, tighten the integrated ODU (or connectorized antenna) mountings. To ensure that the action of tightening does not alter antenna alignment, continue to monitor received signal level.

The ODU emits audible tones during installation to assist with alignment. The pitch of the alignment tone is proportional to the received power of the wireless signals. Adjust the alignment of the unit, in both azimuth and elevation, until the highest pitch tone is achieved.  The tones and their meanings are described in Table 6-5. In each of the states detailed in the table, align the unit to give the highest pitch tone.

See Diagnostics calculated over time on page 7-23. This is calculated from: Power received by the vertical antenna input (dB) ÷ Power received by the horizontal antenna input (dB) V/H Ratio is an aid to debugging a link. If it has a large positive or negative value, then investigate the following potential problems: An antenna coaxial lead may be disconnected. When spatial diversity is employed, the antenna with the lower value may be pointing in the wrong direction. When a dual polar antenna is deployed, the antenna may be directed using a side lobe rather than the main lobe. When there is a reflection from water on the link and spatial diversity is employed, then one expects large, slow swings in V/H Ratio. This indicates the antenna system is doing exactly as intended. Transmit Data Rate The maximum, mean, minimum and latest measurements of Transmit Data Rate (Mbps). See Diagnostics calculated over time on page 7-23. Receive Data Rate  The maximum, mean, minimum and latest measurements of Receive Data Rate (Mbps). See Diagnostics calculated over time on page 7-23.

Test Et he r net  pack et  e r r ors report ed by m ana ged sw it ch or  rout er  If the ODU is connected to a managed Ethernet switch or router, it may be possible to monitor the error rate of Ethernet packets. Please refer to the user guide of the managed network equipment. The test has passed if the rate of packet errors reported by the managed Ethernet switch or router is less than 10 in 1 million packets.
PTP 250 User Guide  Testing link end har dware   phn- 2182_002v000   May 2011   8-9  Test ping pa cket  loss Using a computer, it is possible to generate and monitor packets lost between the PoE power supply and the ODU. This can be achieved by executing the Command Prompt application which is supplied as standard with Windows and Max OS X operating systems. To test ping packet loss, proceed as follows: 1   Ensure that the IP address of the computer is configured appropriately for connection to the ODU under test, and does not clash with the IP addresses of other devices connected to the network. 2   If the PoE power supply is connected to an Ethernet switch or router then connect the computer to a spare port, if available. 3   If it is not possible to connect the computer to a spare port of an Ethernet switch or router, then the PoE power supply will need to be disconnected from the network in order to execute this test. CAUTION The following steps will disrupt network traffic carried by the ODU under test: Disconnect the PoE power supply from the network. Connect the computer directly to the LAN port of the PoE power supply. 4   On the computer, open the Command Prompt application. 5   Send 1000 ping packets of length 1500 bytes. The process will take 1000 seconds, which is approximately 17 minutes. If the computer is running a Windows operating system, this is achieved by typing: ping –n 1000 –l 1500 <ipaddress> where <ipaddress> is the IP address of the ODU under test. If the computer is running a MAC operating system,  this is achieved by typing: ping –c 1000 –s 1492 <ipaddress> where <ipaddress> is the IP address of the ODU under test.

This is reported by Command Prompt on completion of the test. The test has passed if the number of lost packets is less than 2.  Test resist a nce a t  t he PoE e nd of t he drop cable If the above procedures fail to diagnose the issue, there may be a fault in the wiring of the drop cable that connects the ODU (or LPU) to the PoE power supply. Perform this task to test the resistances between the RJ45 pins. Use the PTP drop cable tester (Figure 8-4) to make testing easier. This can be ordered from http://www.motorola.com/ptp/support by selecting Order Cable Tester and completing the order form. NOTE The values printed on the PTP drop cable tester do not apply to the PTP 250. Figure 8 - 4   Drop cable test er ( front  and back views)    Unplug the drop cable from the DATA & POWER OUT port of the PoE power supply. Connect the drop cable tester to the end of the drop cable. Then, perform the tests described in Table 8-1.  Record the results in the Result column, if this is helpful.
